- done a regression on Tool Tab default text. It somehow delete Tools in certain scenarios so I got rid of it

- fixed bug in multigeometry geometry not having the bounds in self.options and crashing the GCode generation
- fixed bug that crashed whole application in case that the GCode editor is activated on a Tool gcode that is defective.
